Each board uses the TPA3116D2 chip and is sized at 79 × 54 × 16 mm, making them easy to mount inside enclosures or test rigs. The kit includes two identical mono boards, useful for bridging into stereo systems or powering two separate drivers.\u003c\/p\u003e\n\n\u003ch3\u003eHow much power does each board deliver and what supply does it require?\u003c\/h3\u003e\n\n\u003cp\u003eEach mono board is rated to deliver up to 100W output power, depending on speaker impedance and supply voltage. The amplifier runs from DC 12–26V, giving flexibility to use sealed lead‑acid batteries, common DC adaptors, or regulated bench supplies for different power levels.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eOutput: up to 100W per board (subject to load and voltage)\u003c\/li\u003e\n  \u003cli\u003eVoltage range: DC 12–26V (nominal operation at 12–24V)\u003c\/li\u003e\n  \u003cli\u003eCompatible with 4Ω or 8Ω drivers — power varies by impedance\u003c\/li\u003e\n  \u003cli\u003eTwo boards included for stereo or dual‑amp setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat audio quality and protection features are included?\u003c\/h3\u003e\n\n\u003cp\u003eThe TPA3116D2 chip is known for efficient Class‑D amplification with low distortion and a high signal‑to‑noise ratio. These HiLetgo modules report a high SNR (around 100 dB), which helps keep background noise low and preserves dynamic detail when paired with suitable transducers.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eChip: TPA3116D2 digital Class‑D amplifier\u003c\/li\u003e\n  \u003cli\u003eSNR: ~100 dB for low noise floor\u003c\/li\u003e\n  \u003cli\u003eCompact PCB layout for minimal parasitic noise pickup\u003c\/li\u003e\n  \u003cli\u003eTypical protections (thermal\/current) depend on board implementation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I integrate these boards into my speaker or electronics project?\u003c\/h3\u003e\n\n\u003cp\u003eIntegration is straightforward: provide a DC supply within the specified range, connect the audio input (line level) and speaker output, and mount the module so heat can dissipate. The small footprint and standard terminal pads make them suitable for mounting inside sealed cabinets, desktop enclosures, or portable powered boxes.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eBoard size: 79 × 54 × 16 mm for easy enclosure fitment\u003c\/li\u003e\n  \u003cli\u003eConnectors: solder pads or screw terminals (depending on variant)\u003c\/li\u003e\n  \u003cli\u003eAudio input: line-level source (preamp, DAC, phone output)\u003c\/li\u003e\n  \u003cli\u003eCooling: allow ventilation or attach to a chassis for heat sink benefits\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat comes in the package and what should I check before powering up?\u003c\/h3\u003e\n\n\u003cp\u003eThe package contains two identical HiLetgo TPA3116 100W power amplifier boards. Before powering them, confirm your power supply voltage and current capability, check speaker impedance, and verify wiring polarity to avoid damage or poor performance.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eIncluded: 2 × TPA3116 100W power amplifier boards\u003c\/li\u003e\n  \u003cli\u003eVerify DC supply between 12–26V and sufficient current headroom\u003c\/li\u003e\n  \u003cli\u003eMatch speaker impedance (4Ω\/8Ω) to expected power output\u003c\/li\u003e\n  \u003cli\u003eInspect solder joints and mounting to prevent short circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Hobbyists, audio DIYers, and electronics builders who want a compact, efficient mono amplifier for custom speaker enclosures, portable PA speakers, or experimental audio projects will find these HiLetgo TPA3116 boards useful. They suit users comfortable with basic wiring and mounting inside enclosures, and anyone seeking a cost‑effective way to power drivers with a modern Class‑D amplifier chip. If you need stereo output, use the two boards as left and right channels or combine them for different system topologies.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can these boards run from a 12V battery?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
